ABSTRACT:
A system for conducting a virtual audio-visual conference between two or more users comprising two or more client stations each acting as a signal source and destination for each respective user, having a user interface for audio-visual input and output including audio signal reception and generation means for receiving and generating audio signals, one or more servers, and a network coupling the client stations and the servers, wherein each user is represented as a corresponding movable visual symbol displayed on the user interfaces of all coupled client stations and the audio signal of all users is generated at each client station with an attenuation according to the spatial position of the respective symbols on the user interfaces and according to the direction in which each movable visual symbol of each signal source is oriented on the user interface.
